DV/DT immunity and recovery time capability of 1.0 cm 2 …

Abstract: The silicon carbide SGTO is a future switching component technology of interest to the Army for various pulsed power appliions. The research presented in this paper investigates the dV/dt immunity and recovery time (T q) capability of 1.0 cm 2 silicon carbide (SiC) super gate turn-off thyristors (SGTOs).

Silicon Carbide Emitter Turn-off Thyristor (SiC ETO). …

And those power levels are the highest in silicon power devices and are comparable to those of the gate turn-off thyristor (GTO). Compared to the conventional GTO, the ETO has much shorter storage time, voltage controlled turn-off capability, and much larger reverse biased safe operation area (RBSOA).

Silicon carbide optoelectronic switches - SPIE

We report the first optical triggering of a silicon carbide thyristor into the latched-on state. This switching is characteristic of electrically triggered thyristors, however the optical triggering produced a significantly faster risetime, 370 picosecond, than is possible with electronic triggering.

It is ideal for the Silicon Carbide Elements to have their heating sections centered in the furnace chaer so that no portion of the heating section extends into the furnace wall. For heat to be radiated properly and the temperature to be maintained, a conical or truned cone-shaped recess inch deep is provided on each interior wall where the element passes through.
